The laminating process is a surface processing technology after printing, and it is also called post-printing plastic, post-printing glue or post-printing lamination, which refers to covering a layer of 0.012～0.020mm on the surface of the printed product with a laminating machine. Thick transparent plastic film to form a paper-plastic integrated product processing technology. Generally speaking, it can be divided into two types, namely coating film and pre-coating film, according to the process used. According to the different film materials, it can be divided into two types: bright film and matt film. The main problems that affect the laminating process: affecting the health of the operators, there is a fire hazard; the paper and film materials after the laminating are difficult to recycle, and resources are wasted.
- Cold laminating: The method of laminating the protective film on the surface of the picture by cold pressing at room temperature is called cold laminating. Among them, there are single-sided mounting and double-sided mounting. In the operation method, there are also manual peeling and self-removing film mounting. The cold laminating process has the characteristics of simple operation, good effect and low cost. It is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.
- Thermal mounting: the mounting method of a dedicated thermal film on a device heated to a certain temperature (about 100-180°C) is called thermal mounting. It can be divided into single-sided thermal mounting and double-sided thermal mounting. It has good permeability and water resistance, good heat resistance, and strong hardness. It is suitable for the post-production of advertising pictures relying on lighting or other occasions. However, heat lamination equipment and consumables are more expensive, complicated to operate, high energy consumption, and have high cost.
- Vacuum laminating: the film and the painting room are vacuumed with a special vacuum laminating machine and then shaped at a certain temperature to complete the laminating. The operation method is complicated, the cost is high, and the picture size is limited, but the mounting quality is high, and the picture texture is strong, which is suitable for photos.
